A maker of frozen meals claims that the average caloric content of its meals is 800 and the standard deviation is 25. A researcher tested 12 meals and found that the average number of calories was 873 with a variance of 22. Is there enough evidence to reject the claim? Assume equal sample size for the control and experimental groups.
